Changing project MCU target

The project MCU target defines the build and debug settings for your target device. When debugging, this MUST match the actual target you are connecting to. For example, you cannot have your project target type set to LPC1768, but you try to debug your application on an LPC1754.

To change your project MCU target type:

select your project in Project Explorer

Right-click on the project and select Properties

Expand C/C++ Build and select MCU Settings

Select the correct target device from the list

Press OK

Note that if you change the MCU family (for example from an LPC17xx to an LPC13xx), rather than just the MCU being used from within a single family (for example an LPC1768 to an LPC1754), then you will also need to replace the startup code used by the project. This simplest way to do this is to create a new project with the required target MCU and copy the startup file across.

Tip

The project target MCU is displayed in the status bar in the bottom right-hand corner of the IDE. The MCU Settings dialog (described above) can be opened by holding down the keyboard Ctrl button and using the mouse to click on the MCU name. For more information, please see the FAQ Status bar shortcuts.
